Patented Apr. 30, 1912-'.

Application filed September 6, 1911. Serial No. 647,991. i

To all whom 'it may concern:

Be it known that I, JACOB THISSEN, citizen of the United States,residing at Kane, in the county of McKean and State of Pennsylvania,have invented certain new and useful Improvements in Resilient Tires, ofwhich the following is a specification.

This invention comprehends certain new and useful improvements inresilient tlres,

andthe Ainvention has for its primary object a simple, durable andeiiicient construction of tire which will possess substantially all ofthe characteristics that are incidental to the ordinary pneumatic andcushion rubber tires, Without the accompanying liability to becomepunctured and otherwise damaged in service, and the invention also hasfor its object to generally improvetires of the lspring type and t'orender them more useful and commercially desirable. l

With'` these and other objects in view as will more fully appear as thedescription proceeds, the in" ion consists in certain constructions, argements and combinai tions of the parts thaytI shall hereinafter fullydescribe and'claim.

Fora full understanding of the invention, referencev is to be had tothefollowing description and accompanying drawings, in which:

Figure 1 is a side elevation of a wheel equipped with my improved tire;Fig.2 is an enlarged transverse sectional view through the tire; Fig. 3illustrates some of the detail parts det-ached in juxtaposition to eachother; and. Fig. 4 is an enlarged longitudinal sect-ion of a portion ofthe tire.

Corresponding and like arts are referred to in the followin descriptionand indicated in all the views o the drawings by the same referencecharacters.

Referring to the drawings, the numeral 1 designates the hub, 2 thespokes, and 3 the felly of a wheel, all of these parts being of anyconventional or desired type and construction.

Encircling the felly 3 is a preferably steel channeled inner rim 4 whichcarries any desired number of transversely extending channeled blocks 5formed integrally therewith or secured thereto in any desired way.Inzthe present instance these blocks are secured to the rim 4 bythreaded pms 6 formed intermediate of their ends with retaining collars7 and preferably screwing into the felly 3 so as to not only secure theblocks 5 to the rim, but to also assist in securing the rim to thefelly.' Preferably,

tapering tubes 8 are mounted within the channeled blocks 5, said tubesin the present instance being arranged in transversely disposed palrs,as best illustrated in Fig. 2, and

being formed at their inner ends with headsl 9 which fit snugly in thechannel blocks 5, whereby they are prevented from turning therein. Theouter ends of the pins 6 project into the tubes 8, as shown. The tubes 8are encircled by helical springs 10, the inner ends of said springsbearing upon the heads 9 of the tubes and the springs being held thereonby means of yoke plates 11, the recessed ends 12 of which engage theinner ends of the springs, as shown, and thereby vsecurely hold themupon the heads 9. The

yoke plates 11 are held in place by pins 13 passing through apertures 14formed in the yoke plates and passing through the blocks 5 and screwingin the felly 8, the pins 18 be'- ing formed intermediate of their endswith collars 15 that bear againstthe yoke plates' and being provided'attheir outermost ends with square or other many-sided heads, whereby awrench may 4be easily applied thereto. It Willthus be seen at this pointthat the yoke plates 1l not only secure the inner ends of the springs inplace, but also serve to securely hold the tubes 8 inthe channeledblocks 5.

The outer rim of my improved tire is spaced from the inner rim 4 andcomprises any desired number of transversely bowed segmental plates 16that are formed with side flanges 17 and that slightly overlap at .theends, as best illustrated in Fig. 3, the

overlapping ends being correspondingly chamfered 4for this purpose, asindicated at 18. At points corresponding to thelocation of the channeledblocks 5, these plates 16 are formed with transversely extending anges;

19 arranged in pairs, and the outer ends of the springs 10 are receivedbetween said flanges and are held therein by yokeplates 20 correspondingto thel yoke plates 11. The plates 20 are secured 1n place by retainingpins 21; Y

22 designates pins that are complemental to the pins 6, the pins 22being preferably secured by lscrew threaded engagement in the plates 16and having their inner ends mounted for radial movement in the outerends of the tubes 8. In addition to their function as guide pins, thepins 22 serve as non-skid devices, their outer ends being preferablybeveled, as at 23, to form spikes or spurs which project from the treadservice of the tire. Between every two pairs of pins 22, in thepreferred embodiment of the invention, .are a number of correspondingbut preferably shorter pins 24, screwthreaded at their inner ends towork in the' plates 16 and thereby be held in position.

v In order to assist in holding the parts in position as againstcircumferential strain, I have provided chains 25 that extend ob liquelyfrom the outer rim to the inner rim, said chains in the'present instancebeing hooked at their ends, as at 26, the vhooked end links beingsecured in openings formed in the flanges 19 and flanges of thechanneled blocks 5, respectively. There are two of these chains providedfor each spring and its correlated parts. y

In order to protect the parts from dust and to add to thev attractiveappearance ofthe tire, I provide a casing which in the presentembodiment of the device consists of side plates 27 secured in anydesired way to the opposite sides of the rim 4 and felly 3, and a treadelement 28 of leather or any other desired substance or material, theside edges of said tread element being clamped in between the outersides of the plates 27 and rings 29, screws or similar fasteningdevices, vas indicated at 30, passing through the. side plates 27, rings29 and interposed leather or the like.

Preferably, the plates 16 are somewhat fiat, transversely considered,and the space between said plates and the tread element 28 is taken upby a filling 31 of cotton yarn or any other substance, so as to impart aproperly rounded tread surface and at the same time add somewhat to theresiliency of the device, although it is to be understood that theinvention is not limited to this construction and arrangement of parts,as the resiliency is obtained primarily by the springs 10 interposedbetween the inner and outer rims of the tire.

From the foregoing description in connection with the accompanyingdrawings, the operation of, my improved spring tire will be apparent.

the practical use of the device, any

"stress or 'shock imparted to the tread surface of the tire at any pointwillcause the pins 22 at such point to move inwardly in the tubes 8, thecorresponding springs l0 being thereby compressed. It is obvious thatthe chains 25 add to the stability of the tire, while at the same timethey do not detract in any wise from the spring characteristics thereof.

While the accompanying drawings illustrate what I believe to be thepreferred embodiment of my invention, it is to be under: stood that theinvention is not limited there to, but that various changes may be madeiin the construction, arrangements and proportions of the parts withoutdeparting from the scope of the invention as defined in the appendedclaims.

Preferably, the side plates 27 are connected together at any desiredintervals by tie bolts 35, said bolts being encircled by tubes 36 withinthe casing, the ends ofthe tubes abutting against the inner or opposingfaces of the side plates 27, whereby the casing is reinforced againstspreading and 'crushing strains.

Having thus described the invention, what is claimed as new is:

l. A spring tire, embodying aninner rim provided with a plurality oftransversely extending channels, pins projecting out- .wardly in aradial direction from said rim in said channels, tubes mounted in saidchannels over the pins and held inthe ychannels, an outer sectional rim,pins projecting inwardly from the sectional rim and working in the outerends of said tubes,l and springs encircling said pins and tubes.'

2. A tire, embodying an inner rim pro vided with a plurality oftransversely extending channeled blocks, an outer sectional rim providedwith a plurality of correspondingly'located blocks, the sides of saidblocks being formed with apertures, chains having hooked ends engagingin thesides of the channeled blocks, the chains extending obliquely, asspecified, and springs interposed between said rims. v i

In testimony whereof I afix my signature in presence of two witnesses.
